Re: Bison and C++

[Richard Stallman]

    One question I think is interesting though, is if one can put info into the
    debug .sym files so that it is possible to GUI debug the original .y and .l
    files.

I don't know what .sym files are--if they are some Macintosh-specific
thing, then for GNU they are just a side issue of a side issue.
However, GDB understands how to refer to the .y file, because of the
#line directives that Bison outputs.  If that doesn't work on a
Macintosh, that would seem to be a bug in their system.
